Spain’s Crown Prince Felipe and his wife have visited Santiago de Compostela, where a train crash has left at least 78 people dead.

They met survivors of Wednesday’s disaster, as well as local residents and emergency workers.

“The Princess and I have come to Galicia, to Santiago, to share the grief of the families and friends who have lost loved ones. This is the main reason,” said Felipe.

“We want all of them to know we mourn with them, we are profoundly sad, we want to give our support in these tough times with care and love.”

Spanish police are investigating whether the driver of the train had been operating it at a reckless speed when he took a tight curve. He has been placed under arrest and has reportedly declined to give police a statement.
